Summary: clang crashes on valid code at -O1 and above on
x86_64-linux-gnu: Assertion `N->getOpcode() !=
ISD::DELETED_NODE && "DELETED_NODE in CSEMap!"' failed
Product: clang
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: -New Bugs
Assignee: unassignedclangbugs at nondot.org
Reporter: su at cs.ucdavis.edu

Classification: Unclassified
The current clang trunk (as well as 3.6.x and later) crashes when compiling the
following test case on x86_64-linux-gnu at -O1 and above in both 32-bit and
64-bit modes.
This is a regression from 3.5.x.
